The way we fuel our bodies with the food we eat are affected by our genetic make-up. The old adage “you are what you eat” plays a major role in determining our health and wellbeing. Food and its nutrients directly and indirectly inﬂuence our gene expressions. Genetic variations aﬀecting certain metabolic traits in turn dictates dietary needs and requirements for instance, the response to food varies from individual to individual explaining why some people can eat as much as they want and never gain weight. These factors may be attributed to the large role that genes play in inﬂuencing eating behaviours and metabolism of diﬀerent foods.
